LONDON — BlackBerry maker Research in Motion is considering splitting its business in two, separating its struggling handset manufacturing division from its messaging network, The Sunday Times reported.

RIM, which last month said it had hired JP Morgan and RBC Capital to look at its strategic options, could break off its handset division into a separate listed company or sell it, the British newspaper reported without citing sources.

Potential buyers would include Amazon and Facebook , it reported, adding that RIM’s messaging network could also be sold, or opened up to rivals such as Apple (AAPL) and Google (GOOG) to generate income.

An alternative option would be to keep the company together but sell a stake to a larger technology firm such as Microsoft , the newspaper said.

Three women have told the New York Times that music mogul Russell Simmons raped them, the latest in a cascade of serious allegations of sexual misconduct against powerful men in entertainment, media, politics and elsewhere.
